Soil nailing is a technique used to bring soil stability in areas where landslides might be a problem. Soil nail can prevent landslides by
inserting hollow bar or steel reinforcement bar into the soil and anchoring them to the soil strata. It is called Soil Nail , because it’s like having a nail being hammered into the soil, where the nails, are the steel bars.
Depending on the complexity of the work, soil nailing can be ranging between $80 per square feet up to $200 per sf. Some contractors will use a software called Snail Plus to determine their soil nail design and complete preliminary assumptions on the soil nailing.Soil nailing technology is an emerging retaining support, firstly used in tunnel and landslide management. The compound of soil layer and soil nail is used to resist soil pressure and other additional loads, then protect excavation face’s stability. While spraying concrete to provide constraining force for deformation among soil nailing.
At present, many supporting methods have great effect in good geological conditions, while in soft and complex conditions, such as crushing, high ground stress in tunnels with great deformation, the challenge for these supporting method is quite big. So soil nailing support at home and abroad is moving to the effect of improving anchoring force, efficiency of support and expanding application range.

Soil nailing support - It ensures the anchoring effect in complex ground conditions. It’s safe, reliable and efficient.This kind of product is suitable for broken rock, loose soil and conditions which are difficult to drill holes, such as fracture zones, decayed rock,gravel, sandy gravel, backfill ground.The soil nail system are an efficient, economical, and simple solution to enhance reinforcement for mining,tunneling,hydroelectic and civil construction.Overall Soil nail is superior for the tunnel construction and it gives enhanced suitability for all types of geographical cuts with using variety and suitability of bolts.
